Unfortunately that happens.My husband went through all his treatment and at the end of it he had four tumours in his lungs that weren't there when he started.If the cancer has already got into the lymph glands before it is detected then this is not unusual.It sounds as if the treatment she is getting is chemotherapy of some description,as this can be used to slow down or arrest the growth of the lung tumours.Is she at home?and how is she physically? Has she lost a lot of weight?can she take nutrition by mouth or does she have a feeding tube?is she active or is she sleeping a lot?and how does she feel about all this information?
